Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Analyses for the NSTX upgrade serve two main purposes. The first is supporting the design of new components, principally the centerstack. The second is qualifying the existing components for higher loads, which increase by a factor of four. Two areas representing this effort are presented: analysis of the current distribution in the new centerstack TF inner coils, and analysis of the support structure for the existing TF outer coils. The current diffusion analysis determines the temperature rise, thermal stress and required active cooling parameters. The TF structural analysis aids in the truss design while quantifying the machine loads and stresses.
